Ask HN: would you be interested in a mobile app updated on a daily basis that combines information from social media (Google, Twitter, Facebook, Wikipedia etc.) and from implied option prices in exchange traded markets (stocks, bonds, currencies, commodities) to identify potential risk in those markets?
Alphaville:" Getting a lot of banks involved in an IPO has a side benefit: it subdues the potential for criticism. Every firm brought into the tent by an issuer, beyond a vested interest in being nice, has to abide by the rules. In the US, these include a blackout period for publishing research of 40 days for lead underwriters and 25 days for everyone else.
With SpaceX using 23 banks for its capital raise, independent research about the record-breaking float has been very hard to come by. That alone is our reason to raise awareness of a couple of notes from the team at Morningstar.
Their headline findings are:
The stock’s probably worth $63 per share, a 53 per cent discount to the $135 issue price.
SpaceX probably has an addressable market of about $129bn, rather than the $1.6tn claimed in its S-1 filing.
In a (metaphorical) moonshot scenario, where SpaceX pioneers orbital data centres and captures 20 per cent of AI computing capacity by 2040, the company would be worth $1.97tn, or $154 per share.
Morningstar assigns only a 7 per cent per cent chance of the moonshot scenario happening.
For Starlink, Morningstar estimates the global market to be worth about $129bn, which is rather less SpaceX’s estimate of $1.6tn. “[T]echnical constraints and unit economics limit the business primarily to lower-density markets,” it says.
Space cadets and attached bankers, do please tell us in the comments what Morningstar gets wrong."
TLDR: "...results of these causal estimates of employment effects is that fiscal incentives for data centers cannot be justified on the grounds of job creation"
Calcining Mg(OH)₂ -which is what you find in seawater -
converts the soft compound into magnesium oxide, a valuable mineral commonly used in refractories, catalysts, and ceramics.The Chemical Equation: \(Mg(OH)_2 \xrightarrow{\Delta} MgO + H_2O\)Temperature Requirements: You need to heat the magnesium hydroxide to a temperature range between 500°C and 900°C. Heating at the lower end (around 500°C) yields a highly reactive, porous form of nano-MgO, while heating above 1,200°C creates "dead-burned" MgO used in high-heat industrial bricks.The Yield: The weight of your final MgO product will be roughly 69% of the original Mg(OH)₂ mass, as the evaporated water accounts for the 31% weight difference.
Already energy intensive. To get to magnesium ore is another step.
"I have long felt airlines should simply charge two fees: one for volume (i.e. economy/business class, etc.), one for weight (person plus all bags, checked or carry-on)."
Couldn't agree more. More often than not I have found myself paying for a seat with more legroom only to find myself next to a person twice my "width" and weight and significantly impacted in my comfort because of it. If say the statistical average https://www.cdc.gov/nchs/fastats/body-measurements.htm
would serve as a baseline for charging more if above, perhaps that might work.
The mystery airman who nobody has seen or heard of since. Who climbed 7000 feet up a mountain, severly wounded of course, while surrounded by enemy fighters. And they still managed to identify his heartbeat and rescued him. Amazing!
